It is what I tried to show on comment #3, where I see that the *kernel* is throwing the following error: Feb 15 19:48:58 ubuntu22-vm kernel: Code: ff ff 00 45 31 db 48 8d 15 c9 ac = 00 00 4c 8d 05 46 8f 01 00 4c 8d 2d 1f 8f 01 00 49 89 c2 48 8d 58 ff 48 89 f8 = 49 f7 da 66 90 <8b> 08 83 f9 07 77 19 85 c9 74 45 83 f9 07 77 40 48 63 0c 8a 4= 8 01 Feb 15 19:48:58 ubuntu22-vm kernel: p64[1403]: segfault at 0 ip 00007ff10dcb7350 sp 00007ffd5a54b570 error 4 in ld-linux-x86-64.so.2[7ff10dc97000+2a000] This means the resulting image can not execute the entry point after the ke= rnel loads both dynamic loader and the binary for some reason. You can check that even with gdb, I can even start to execute the first instruction (starti).= =20=20 I think you will need to check why binfmt loading code in kernel is doing differently; or, most likely, fix the bogus binary. --=20 You are receiving this mail because: You are on the CC list for the bug.=
